Benefits of technology

[0006]In one embodiment, and by way of example only, a method of reducing artifacts in a near-to-eye (NTE) display that is worn, at least partially, on a viewer's head, includes sensing movement of the NTE display while displaying an image that comprises individual content frames on the NTE display. A characteristic of the individual content frames of the displayed image is varied based on the sensed movement.

Problems solved by technology

One of the potential drawbacks associated with NTE devices is that the virtual image may fail to “stick” to the remotely located surface during movements of the viewer's head, resulting in image blur or the display of so-called image artifacts.
During these flight conditions, viewer head movements may be unavoidable.

Abstract

A near-to-eye (NTE) display system and method are provided for reducing artifact display in a NTE display that is worn, at least partially, on a viewer's head. The movement of the NTE display is sensed while displaying an image that comprises individual content frames on the NTE display. A characteristic of the individual content frames of the displayed image is varied based on the sensed movement.

Description

TECHNICAL FIELD[0001]The present invention generally relates to near-to-eye (NTE) displays and, more particularly, to systems and methods for reducing display artifacts in NTE displays.BACKGROUND[0002]Modern vehicles, such as aircraft, often include head-up displays (HUDs) that project various symbols and information onto a transparent display, or image combiner, through which a user (e.g., the pilot) may simultaneously view the exterior. Traditional HUDs incorporate fixed image combiners located above the instrument panel on the windshield of the aircraft, or directly between the windshield and the pilot's head.[0003]More recently, “head-mounted” HUDs have been developed that include near-to-eye (NTE) display devices. Depending upon the particular end-use environment, these NTE display devices may be coupled to a helmet or headset of viewer, and thus move with the changing position and angular orientation of the viewer's head. This advantageously allows the displayed information to...
